Hop the yo-yo into the air
with a slight jerking motion. Aim the thumb from your non-throwhand
towards the inside of the yo-yo and land it on the edge. Allow the
yo-yo to precess around.

Just as the yo-yo turns sideways bring the thumb
from your throwhand in towards the yo-yo, and transfer it over. Continue
the thumb grind allowing it to completely precess around.Note:It sometimes helps to grab the string and hold it
away to keep it from grabbing the yo-yo.

As it comes completely around toss it off your
thumb and return to the hand.
